Binding Sites of Automobile Exhaust Gases on Metal–Organic Frameworks: Advances and Perspectives

Automobile exhaust gases are major contributors to air pollution, leading to severe challenges in environmental protection and public health. Metal–organic frameworks (MOFs) have emerged as promising adsorbents to selectively capture gaseous pollutants due to their highly tunable structures, large surface areas, and abundant binding sites. This review delves into the diverse binding sites within MOFs for the selective adsorption and separation of automobile exhaust gases and state-of-the-art technologies for in situ structural characterization. The roles of metal centers, organic linkers, and pore environments in determining adsorption efficiency and selectivity are systematically analyzed. This work provides foundation insights into the design and construction of next-generation MOF-based solid sorbents, representing innovative solutions for automotive emission control and promoting more sustainable transportation systems.
